CAR-ROOF CONSTRUCTION.

Specification of Letters Patent.

Patented Jan. 13, 1920.

Application led December 19, 1916. Serial No. 137,770.

To all whom 'it may concern.'

Bc it known that I, N ATHANIEL S. REEDER, a citizen of the United States, residin in New York city, in the county of New ork and State of New York, have invented oertain new and usef-ul Improvements in Car- Roof Constructions, of'which the following is a specification.

' This invention relates to a new and useful improvement in car roof construction, an ob? ject being to provide a roof combining a maximum of strength and rigidity with a minimum of weight, and which will be simple in construction and capable of 'being manufactured cheaply. I

Another object of the invention is to provide an improved carline which can be manufactured by pressing a rectangular shaped plate into the desired shape, thus obviating the use of expensive blanling dies or the production of scrap metal, such as is usual when such articles are formed from irregularly shaped plates.

Another object of the invention is to provide a roof construction embodying simple and effective means for the attachment and adjustment of the roof sheetsl to the carline, and also having a weather-proofing member which engages the edge portions of the roof sheets.

Another object of the invention is to provide simple means for attachment of the roof sheets and weather-proofing member to the carline which will permit of the easy removal and replacement of such sheets or member.

Another object of the invention is to provide a carline to which the roof sheets may be secured in such a manner as to 'provide weatherproof expansion joints between the rooic sheets of the car. y

A further object of the invention is to provide a carline which is adapted to conduct to the exterior of the car any water which may leak through the joints between the roof sheets.

Referring now to the drawings in which like reference characters referI to like parts,

Figure l is a fragmental plan View of a 'perf tionof a car roof and carline constructed in accordance with the invention; Fig. 2 is a sectional view of the same taken on line 2 2 of Fig. l, the roof sheets and weatherproofing member being extended farther than shown in Fig. 1. Fig. 3 is a detail sectional view taken on line 3--3 of Fig. 1, and Fig. 4 is an end elevation of the carline with the roof sheets and Weather-proofing member removed, and Fig. 5 is an enlarged detail sectional view of a modiication of the roof construction. f

Referring now in ldetail to the drawings, 1 indicates the side plates of the car which may be of any suitable form or construction, but as shown in the drawings are preferablyof Z section. 2 indicates the carlines, each of which is madefrom a lrectangular metal plate preferably bent to form a member of channel or U section having lateral flanges 3, 3 extending outwardly therefrom in opposite directions. This channel shaped member has its deepesty portion at substantially its center, and tapers'to its shallowest portion at each end, whereas thelateral fianges3, 3 are widest at the ends of the carline, and taper toward its center portion where the flanges are narrowest. Fromv an inspection of Figs. 1 and 2 of the drawings, it will be seen that the Width of the anges 3, 3 varies in proportion inversely to the depth of the channel portion of the carline, and it follows that the carline may' be pressed from a plate of rectangular shape having a uniform width throuv hout lts length, thusI making unnecessar t e use of' expensive blanking dies, and o viating the production of scrap metal, as hereinbefore referred to. The end portions of the Hanges 3, 3 are slit, as at 4, 4 for some distance back from the ends of the carline, and the outer portions 5, 5 of the fianges are bent downwardly, as shown in Figs. 2 and 4, until the end portions 6, 6 of such fianges are in the same horizontal plane as the lower surface of the end of thechannel shaped portieri of the carline. The ends of the channel shaped portion 0f the carline may be secured to the side plate by means of rivets 7 or other suitable means, and the downwardly bent portions 5, 5 of the lateral Hanges 3, 3 may also be secured to the side plate by similar means 8, 8.

The roof sheets 9, 9 preferably extend continuously across the width of the car and at their outer edges are provided with downturned flanges or portions 10, which contact g with the vertical portion 11 of the side plate.

It will readily be seen by those skilled in sheets.

theart to which this invention appertains that if a car is desired of the ventilated type, the flanges 10 of the roof sheets may be eX- tended outwardly beyond the vertical portion 11 of the side plate 1 in order to provide a. Space 23 between the flange of the roof sheet and the side plate, through which air may freely pass in and out of the car, thus v,permitting Aefficient ventilation of the car. The edge portions 12 of the roof sheets 9` are turned downwardly and are adapted to extend within the channel portion of they carline 2, when such plates 9 are in their proper position on the carlines, each of the carlines being provided withy a plurahty of members 13, 13, 13 which are secured within v and across the channel portion thereof. The members 13 may be of Z, channel or other suitable shape, and are each provided with flanges 14, which extend longitudinally of the carline, and which may be secured to the webs of the channel portion thereof, as shown in the drawings, by any suitable means. The intermediate portion 15 of these members is provided with a perfoation 16 into which the hooked end 17 of a bolt 18 may be inserted for the purpose of, securing the roof sheetsl and weatherproofing element to the carline.

19 indicates a weather-proofing member which preferably is formed of a metal plate bent to form a shallow channel section having flanges 20,20 extending outwardly and slightly downwardly therefrom in opposite directions. This member 19 extends for preferably the full width of the car, and is provided at intervals with perforations through which the threaded ends of thev I contact with such nuts will hold the flanges 20, 20 in close contact with the roof sheets 9, 9. It will be .seen from the foregoing descri tion that the roof sheets 9, 9 are slidab y clamped or held between the flanges 20, 20 of the elements 19, and the flanges of the carline 2, thus allowing the roof plates to move relative to each other and to the carline when the car has become deformed due to railway service conditions. This construction also permits of the expansion and contraction ofthe roof plates due tions.

to changes in temperature or weather condi- Should any water leak through the joints formed -by the roof sheets 9 and the ling flan flanges 20of the member 19, as above described, due to damage of the member 19 or from other causes, it will drop within the channel portion of the carline 2, and as a resultl of the downward and outward /inclination ofthe web portion of such channel from the longitudinal centerline of the car .to the side of the car the water will be conducted tothe exterior of the ear, a slight l space being provided between the roof sheet .and the side plate at the end of the channel portion of the carline, as shown at 22 in Fig. 2.

lthough in the drawings and foregoing description only portion of one carline and the roof plates and the several parts coperating therewith are illustrated and described, it will `be understood by those skilled in the art that both ends of the carline are substantiallyY alike, and that a railway car roof is composed of a, plurality of such parts.

From the foregoing description, it will 'be seen'that many minor changes in the details and arrangement of arts may be made without departing from t e spirit and 'scope of the invention as defined by the appended claims.

Having thus described the invention, what I .claim as new and desire to secure by Letters Patent is:

1. A roof carline having a laterally extending flange, said flange being bifurcated, and one of the resultant portions bent downwardly.

2. A roof carline having a laterally extending flan e, the end portions of said flange being ifurcated, and one of the resultant portions bent downwardly.

3. A roof carline having a central portion, and. an integral laterally extending bifurcated flange, and one of the resultant portions bent downwardly.

4. A roof carline having abody ortion and a laterally extending' flange, t e end portions of said flange being bifurcated, and one of the resultant portions bent downwardly.

5. A--froof carline having a body portion of substantially U shape and a laterally extendin flange, the end portions of said flange bemg bifurcated.

6. A roof carline having laterally extendthe end portions of each of said flanges eing bifurcated.

7. A roof carline having a `central portion, a laterally extending flange on each side thereof, the end portions of said flanges being bifurcated.

8. A roof carline having a central portion of substantially U shape and a laterally extending flange on each side of said central portion, kthe end portions of saidflanges being bifurcated.

9. A roof carline having a central ortion of substantially U shape, deepest at its cenwassen tet and tapering toward its ends, a flange extending laterally from each side thereof,

said flanges being widest at their' ends and tapering toward their centers, the iend portions of said flanges bein bifuroated.l

10. A roof carline havmg a body portion, a, flange extending laterally therefrom, the end portion of said flange being bifurcated, one of the resultant portions being bent downwardly Jfrom its original plane into the same horizontal plane as-the lower portion of the body.

1l. The combination, with the side plate of a car, of a carline secured thereto, said carline having a laterally extending flange, the end portions of said flange being slit, and a portion of the flange ybent downwardly and secured to said side plate.

12. The combination, with the side plate of a car, of a carline secured thereto, said carline having laterally extending flanges, the end portions of said flanges being split, and portions of the flanges bent downwardly and secured to said side plate, and roof sheets resting upon said flanges and out of contact with the downwardly bent portions of said flanges, said roof sheets having downwardly depending end flanges spaced away from the end of said carline `and web of said side plate.

vIn testimony whereof I affix my signature in the presence of two witnesses.
